I didn't pull the whole airbox out, so I could not look for part numbers. Realoem is not showing any block off breakout on the air box for NA or Euro cars (or for the charcoal filters). My guess is that the air box was changed, so to get the plates you'll need to get new air boxes.

Then while tightening everything up the bit fell down inside the engine. I heard it hit the bottom pan. I assume it will just fall out the drain hole but I'm going to call the service center to ask what they do in those situations.

I don't want to pull the pan off. I know there is not risk. Just mentally knowing what I did will piss me off.
